This thread started as part of a consideration of orthodoxy in The Sand Box (here's a link), which is why the post immediately below this note sounds like it begins in mid-sentence. If you do not already have access to The Sand Box, and would like to, please click here.
The conversation you describe sounds interesting.
The Word can, and in all likelihood has, become flesh many times in many places, without becoming a different Word in any way.
You undoubtedly can guess my response to that observation.
As I have said and written many times, not least at In The Beginning, I am positively convinced -- intellectually and from experience -- that when the Gospels Teacher said (at Matthew 26) of bread "This is my body" and of wine "This is my blood", he never intended for us to conclude he meant "just bread, just wine". He wanted us to understand everything is "My Body", everything is "My Blood".
That was his way of saying what Ibn 'Arabi means by "thou art not thou, thou art He without thou" and what Nisargadatta means by "the entire universe is his body, all life is his life". Indeed, I'm not sure I have come across a single Teacher who does not say the same thing.
Perceiving ourselves and everything else separatively, of course we hear those words similarly, and of course we changed them from being a simple (by which I mean clear, not easy) lesson into do-it-my-way-or-die orthodoxy.
Our tendency to take things literally is a factor here, too. Thus, I am likewise convinced that the Gospels Teacher did not intend for us to memorize the prayer at Matthew 6:9 and pour it in concrete as "The Lord's Prayer". If you read the lines which precede it (not to mention take into consideration his perspective on life), it is clear to me that by "pray then like this", he means something like "in this manner" or "along these lines" or "with this attitude". In other words, don't memorize the words (I mean, even a myna bird can memorize words) but rather understand the principle, get the meaning. Does he not remind us that God already knows what we want anyway, so what we say is not as important as how we say it, why we say it.
So, it isn't that the Word became flesh in or as him and in or as some one or two others, but rather that the Word is flesh. The One is the other. And the more enthusiastically I live my life accordingly, the more apparent is it to me. In a word, live life as if the Truth were True, and we see that it is.
Anyway, so it seems to me.
